Added opaque join-token support across backend and frontend: new migration/model/service/endpoints, guest controllers now resolve tokens, and the demo seeder seeds a token. Tenant event details list/manage tokens with copy/revoke actions, and the guest PWA uses tokens end-to-end (routing, storage, uploads, achievements, etc.). Docs TODO updated to reflect completed steps.
